HD64F3437TF16 Datasheet, PDF (586/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

Table 23.3 DC Characteristics (4-V Version)
Conditions: V_CC = 4.0 V to 5.5 V, V_CCB = 4.0 V to 5.5 V, AV_CC = 4.0 V to 5.5 V^*1,
AV_ref = 4.0 V to AV_CC, V_SS = AV_SS = 0 V, Ta = –20˚C to +75˚C (regular
specifications), Ta = –40˚C to +85˚C (wide-range specifications)
